NOTES: <br /> 1 When more than one detection was made within the contoured interval,the detected concentrations were added together <br /> and an average concentration was calculated. If the analytical results of one of the samples analyzed within the contouredS!o <br /> interval was non detect,one half of the detection limit was added to the detected concentrations in the other samples and N <br /> an average concentration was computed for the contoured interval <br /> 2. If(ND)or positive number(i.e. 16)appears next to a boring or a well,a porton of the interval from 1.0 to 5.5 feet bgs was �1e'?edj <br /> sampled and tested. If no notation appears, no analysis was performed for that interval. The detection limits for the various <br /> Volatile Organic Chemicals analyzed range from 1.0 to 1,500. 41 <br /> 3 Volatile Organic Compounds (VOCs)were analyzed by one of the following methods: EPA Method 8010 usingGas s AOS St`eFt <br /> ohEPAaMethodh8240 using/ tron GC/Masure SpeDetector ctrometeE MS)EPA Method 8020 using GC/Photo Ionization Detector(PID); aa4 AAass <br /> TY976� �TY617 <br /> (ND) (ND) <br /> ' MW-13nPu '•/ f <br /> mpLocation�� it - - <br /> s <br /> - Mw-15B '•1 <br /> I (ND) <br /> A1C Paved Parking Area Station House <br /> + + - +---- TY66 + + +- <br /> —F -�- +---+--F-�-{ND) + + -� -+ TYB19i�-- <br /> -- + --_-+- + -- F- --i- + _._-+--- I + I + -+TY--i- +--•TYB32~ +--+ T--�- +. ._- -- --- <br /> B74 ___. - <br /> -'-- - A/C Paved Road (7-9) (24-1) 4 A/C Paved Road <br /> 1 <br /> TY87 - 19.3)� a d9ND) M(ND) e(ND)'s - ((YW;484 !
